| aotus infulatus monkey is susceptible to plasmodium falciparum infection and may constitute an alternative experimental model for malaria. | aotus is one of the who-recommended primate models for studies in malaria, and several species can be infected with plasmodium falciparum or p. vivax. here we describe the successful infection of the species a. infulatus from eastern amazon with blood stages of p. falciparum. both intact and splenectomized animals were susceptible to infection; the intact ones were able to keep parasitemias at lower levels for several days, but developed complications such as severe anemia; splenectomized monkey ... | 2000 | 10800194 |
| abo blood groups in the primate species of cebidae from the amazon region. | the abo blood groups were determined in blood and saliva collected from 40 aotus infulatus, 74 saimiri sciureus, and 96 cebus apella from the amazonian region along the tocantins river. saliva samples were tested for human abh antigens by a standard hemagglutination inhibition test. aotus infulatus showed monomorphism, exhibiting only the b blood group. saimiri sciureus exhibited the a (67) and ab (7) phenotypes. all four phenotypes have been found in c. apella: o (8), a (52), b (19) and ab (17) ... | 2002 | 12190854 |
| severe anemia affects both splenectomized and non-splenectomized plasmodium falciparum-infected aotus infulatus monkeys. | severe anemia is the earliest and a frequently fatal complication of plasmodium falciparum infection. here we describe aotus infulatus as a primate model suitable to study this malaria complication. both non-splenectomized and splenectomized monkeys receiving different inocula of p. falciparum fvo strain presented large (> 50%) decreases in hematocrit values during infection. non-splenectomized animals were able to control parasite growth (parasitemia did not exceed 4%), but they had to be treat ... | 2003 | 12973537 |
| uterine evaluation and gestation diagnosis in owl monkey (aotus azarai infulatus) using the b mode ultrasound. | gynecological and obstetrical ultrasonography has become an indispensable tool in the routine management, health evaluation and research on captive non-human primates. | 2006 | 16764669 |
| [morphologic and genetic differentiation of night monkey (aotus infulatus, primates, platyrrhinians, cebidae) populations from the right and left banks of rio tocantins (brazil)]. | the cranial morphology of 28 specimens of night monkeys (genus aotus) was examined using three-dimensional geometrical morphometrics. new results of the morphological differences between two populations of aotus infulatus from both banks of the rio tocantins are proposed. these morphological results totally agree with the genetic distinction of these populations proposed by schneider -- and sampaio --, and probably point out recent rapid evolutive changes for this species. our morphometric resul ... | 2007 | 17303542 |
| dna sequencing of 13 cytokine gene fragments of aotus infulatus and saimiri sciureus, two non-human primate models for malaria. | aotus and saimiri are non-human primate models recommended by the world health organization for experimental studies in malaria, especially for vaccine pre-clinical trials. however, research using these primates is hindered by the lack of specific reagents to evaluate immune responses to infection or vaccination. as a step toward developing molecular tools for cytokine expression studies in these species, primer pairs for 18 cytokine gene fragments were designed based on human dna sequences and ... | 2010 | 20943414 |
| hematological, hepatic, and renal evaluation in aotus azarai infulatus. | knowing the physiological ranges of certain hematological and biochemical parameters is necessary for understanding the alterations caused by pathogenic agents and establishing differences between states of health and disease. hematological evaluations and clinical chemistry were performed on livers and kidneys from owl monkeys with different sexes and age ranges. | 2010 | 21044090 |
| qualitative analysis of preputial and vaginal bacterial microbiota in owl monkeys (aotus azarai infulatus) raised in captivity. | the aim of this study was to identify the aerobic bacteria of the preputial and vaginal microbiota in owl monkeys that have been raised in captivity and to evaluate the antimicrobial susceptibility of these bacteria by gender and social organization. | 2012 | 23278502 |
| antiviral activity of chloroquine against dengue virus type 2 replication in aotus monkeys. | dengue virus (denv) of the flaviviridae family is a single positive-stranded rna virus that is transmitted by aedes aegypti and aedes albopictus mosquitoes. the objective of this study was to investigate the use of chloroquine (clq) as an antiviral drug against dengue virus in monkeys. to analyze the action of the drug in vivo, nonhuman primates groups (aotus azarai infulatus) were inoculated with a subcutaneous injection of a virulent strain of denv-2, treated and untreated clq. blood hematolog ... | 2015 | 25664975 |
| analysis of follicular events in owl monkeys (aotus azarai infulatus) using b-mode and doppler ultrasound. | ultrasound (b-mode) was used to analyze follicular events in 12 trained female owl monkeys (aotus azarai infulatus). the animals were examined every 48 hours for over 90 days to measure and map follicular growth in both ovaries and to measure (using doppler velocimetry) local hemodynamic changes during the peri-ovulatory stage. there were 44 follicular growth events, each with two or three follicular waves, and a mean ± sem interval between events of 17 ± 1.13 days. there were various hemodynami ... | 2013 | 23602218 |
| renal evaluation of aotus azarai infulatus by ultrasonography and serum chemistry profile. | this study aimed to characterize anatomical and biochemical properties of owl monkey kidneys in order to provide normal reference values. sixty-nine aotus azarai infulatus (45 males and 24 females) were divided into four different age groups (ag1: 3 months-1 year; ag2: 2-3 years; ag3: 4-6 years; and ag4: over 7 years old). the monkeys were evaluated with a serum chemistry profile, focusing on serum creatinine (scr) and blood urea nitrogen (bun) and with ultrasound. mean body mass differed among ... | 2012 | 22511524 |
| positive selection along the evolution of primate mitogenomes. | the mitochondrial genomes of four neotropical primates, aotus infulatus, chiropotes israelita, callimico goeldii and callicebus lugens were sequenced and annotated. phylogenetic reconstructions with mitochondrial genes of other 66 primates showed a similar arrangement to a topology based on nuclear genes. screening for positive selection identified 15 codons in 7 genes along 9 independent lineages, three with two or more genes and five in internal nodes, ruling out false positive estimates. mito ... | 2013 | 23756226 |
| continuous infusion of propofol or intermittent bolus of tiletamine-zolazepam in feline night monkeys (aotus infulatus). | although commonly used, dissociative anesthesia results in unsatisfactory and long recovery periods. the intravenous anesthetic propofol seems to be the most advantageous solution. the objectives of this study were to investigate the required infusion rate of propofol to maintain surgical anesthesia and to compare it to tiletamine-zolazepam in aotus infulatus. | 2014 | 24236814 |
